1 Claim. (Cl. 30-68) The invention relates to new and usefulimprovements in razors, more particularly in razors having a triangularhead. The conventional safety razor, while relatively efiiicient inshaving smooth areas and the like, leaves much to be desired whenshaving the upper lip, around the nose, cleft chin and the like.

Furthermore, the conventional razor, when used normally, obstructs theview of the user considerably.

The invention overcomes these disadvantages by providing a razor with atriangular head, said razor having novel means for attaching anddetaching the head from the body thereof and which enables the blade tobe changed readily and which furthermore permits the razor to be rinsedclean with the minimum of effort.

The principal object of the invention is to provide a razor of thecharacter herewithin described which, due to the configuration of thehead, enables the user to have a clearer view of the area being shaved.

Another object of the invention is to provide a device of the characterherewithin described which is particularly suited for use for shavingthe hair from the upper lip, around the nostrils and under the arms,etc.

A yet further object of the invention is to provide a device of thecharacter herewithin described which, due to the configuration thereof,is particularly suitable for hospital use wherein the patient is beingprepared. for operation.

Another object of the invention is to provide a device of the characterherewithin described in which the head can be released and secured byone hand and in which the thumb release is held firmly in place by aspring within the barrel of the razor.

Still further object of the invention is to provide a device of thecharacter herewithin described in which the head can be released andraised by spring pressure sufficiently to rinse same clean but withoutfully detaching the head from the body portion.

With the foregoing objects in view, and such other objects andadvantages as will become apparent to those skilled in the art to whichthis invention relates as this specification proceeds, and consistsessentially in the arrangement and construction of parts all ashereinafter more particularly described, reference being had to theaccompanying drawings in which:

Figure l is a side sectional elevation of the device with the head inthe open or detachable position.

Figure 2 is a view similar to Figure l but fragmented in part andshowing the head in the secured position.

Figure 3 is an enlarged fragmentary portion of the side of the barrelwhere the thumb lever is pivoted thereto.

Figure 4 is a perspective view of the detachable head parfay.

In the drawings like characters of reference indicate correspondingparts in the different figures.

Proceeding therefore to describe the invention in detail, it will beseen from the accompanying drawing that provides an elongated hollowhandle 1 which preferably tapers inwardly from the base 2 thereoftowards the States Patent 9 i Patented Mar. 7, 1961 upper end 3 thereoffor convenience. A substantially triangular base head 4 is securedtransversely across the upper end 3 of the handle, the said base headbeing apertured as at '5 and being provided with a pair of projections 6extending upwardly from the upper face 7 thereof, the purpose of whichwill hereinafter be described.

A complementary blade clamping head 8 is adapted to be received upon thebase head 4, said blade clamping head being concavo-convex as clearlyshown in Figure 4 and this head is apertured as at 9, these aperturesbeing adapted to engage over the projection 6 when the head is in theblade clamping position shown in Figure 2.

A stem or shank 10 is secured to the underside of the blade clampinghead 8 and extends downwardly therefrom substantially at right angles tothe head, said shank being adapted to pass through the aperture 5 in thebase head 4 and to enter the hollow handle 1 as clearly shown inFigure 1. An elongated slot 11 is formed through the lower end 12 of the.shank and this permits the selective detachment of the blade clampinghead 8 to the base head4, it being understood that a triangular blade(not illustrated) sharpened on both edges, is adapted 'to be clampedbetween the two heads with the cutting edges exposed along thelongitudinal edges 13 of the Means are provided to permit the selectivedetachment of one head from the other, said means taking the form of ahandle or lever 14 pivoted intermediate the ends thereof between a pairof lugs 15 formed on the side wall 16 of the hollow handle 1 by means ofpivot pin 17. The inner end of the lever 14 is provide-d with a finger18 adapted'to engage within the for'ementioned slot 11 in the stem 10.

The outer end 19 of the lever 14 is curved as shown in Figure 1 and isthereby adapted to nest against the side 16 of the handle when in theblade clamping position shown in Figure 2. In this connection the broadend 20 of the blade clamping head 8 is recessed as at 21 and acomplementary recess (not illustrated) is formed in the same end of thebase head 4, so that the curved portion 22 of the lever 14 nests withinthis recess when in the clamping position shown in Figure 2.

It will be seen from the foregoing that when the lever is in theposition shown in Figure 1, the blade clamping head 8 can be removed andreplaced freely and that when the blade clamping head is in the positionshown in Figure 1, the lever can be moved in the direction of arrow 23,thus causing the finger 18 to engage the slot 11 and draw the bladeclamping head downwardly upon the base head, the projection 6 enteringthe apertures 9 and maintaining the alignment required.

This action is assisted by means of the assembly collectively designated24 and contained within the hollow handle 1. Also formed upon the innerend of the lever 14 is a cam 25 and a hollow carrier 26 is securedwithin the hollow handle 1 by means of a screw plug 27 in the lower end2 of the handle. This carrier contains a resilient spring 28, a lowerball bearing 2? resting upon a transverse pin 30, and an upper ballbearing 31. The wall of the carrier is slotted as at 32 to permit theinner end of the lever 14 to enter within the carrier and the upper ballbearing 31 rests against the cam 25. With. the lever in the positionshown in Figure 1, the cam 25 compresses the spring 28 so that when thelever is moved in the direction of arrow 23, the spring 28, reactingbetween the carrier and the cam, snaps the lever into position andmaintains same in the closed position thus clamping the head 8 firmlyupon head 4.

From the foregoing it will be appreciated that the blades are readilychangeable and that the razor can be washed easily after use.

Since various modifications can be made in the invention as hereinabovedescribed, and many apparently widely different embodiments of same madewithin the spirit and scope of the claim without departing from suchspirit and scope,- it is intended thatall matter. con,- tained' in theaccompanying specification shall beinterpreted as illustrative only andnot in a limitingsense.

What is claimed as the invention is: V

A razor comprising in combination a substantially hollow handle, acentrally apertured base head secured transversely across the upper endof said handle, a blade clamping head complementary to said base headand being detachably mated therewith, a stern secured tothe underside ofsaid clamping head and extending downwardly therefrom, said stem adaptedto enter said hollow handle, an elongated slot formed through said stemadjacent the lower end thereof, means on said handle cooperating withsaid stem adapted to clamp said clamping head onto said base head and torelease said clamping head from said base head selectively whereby saidclamping head can be removed from said base head, said means comprisinga lever pivotally connected intermediate the ends thereof to one side ofsaid handle, the outer end of said lever being curved to nest underneathsaid base head when in the head clamping position, a finger formedadjacent the inner end of said lever selectively engageable within saidslot in said stem, a cam formed on the inner end of said'lever belowsaid finger, the inner side of said cam engaging the lower endof saidstem, a hollow carrier detachably secured within said handle below saidlever, a resilient spring in said carrier, ball means also in saidcarrier above said spring, said ball means engaging the outer side ofsaid cam, said spring reacting between the base of said handle and saidball, said spring, said ball, and said cam cooperating together toprovide an over center snap action to said lever whereby said stem isurged upwardly free of said finger in one position ofsaid lever,and-urged downwardly into head clamping position in the other positionof said lever.
